Unlike Vδ1 γδ-T cells which express lymph node homing chemokine receptor C-C chemokine receptor 7 (CCR7), the circulating Vγ9Vδ2-T cells preferentially express inflammatory homing chemokine receptor CCR5, which can mediate the migration of Vγ9Vδ2-T cells to CCR5 ligands that are expressed in tumor cells (20, 102). This evidence concerns the gene CCR5 and neoplasm.
